Definition of fauces
: the narrow passage from the mouth to the pharynx between the soft palate and the base of the tongue.
What are tonsillar fauces?
The fauces, isthmus of fauces, or the oropharyngeal isthmus, is the opening at the back of the mouth into the throat. It is a narrow passage between the velum and the base of the tongue. … Between these two arches on the lateral walls of the oropharynx is the tonsillar fossa which is the location of the palatine tonsil.
What are the pillars of fauces in the pharynx and their function?
The right and left palatoglossus muscles create ridges in the lateral pharyngeal wall, referred to as the palatoglossal arches (anterior faucial pillars). These pillars separate the oral cavity and the oropharynx — the muscle functions as an antagonist to the levator veli palatini muscle.
What is the Faucial Arch?
(fo’sez) [L.] The constricted opening leading from the oral cavity to the oropharynx. It is bounded by the soft palate, the base of the tongue, and the palatine arches. The anterior pillars of the fauces are known as the glossopalatine arch, and the posterior pillars as the pharyngopalatine arch.
What do the fauces do?
Moving farther into the mouth, the opening between the oral cavity and throat (oropharynx) is called the fauces (like the kitchen “faucet”). The main open area of the mouth, or oral cavity proper, runs from the gums and teeth to the fauces. When you are chewing, you do not find it difficult to breathe simultaneously.
What is the importance of the fauces?
The muscle of the soft palate and the fauces play important roles in swallowing and breathing.
How long is the pharynx in inches?
The pharynx is about 5 inches long, depending on body size. Also called throat.
What is the pharyngeal tonsil?
The pharyngeal tonsils are located near the opening of the nasal cavity into the pharynx. When these tonsils become enlarged they may interfere with breathing and are called adenoids. The palatine tonsils are the ones that are located near the opening of the oral cavity into the pharynx.
What does Faucial mean?
verb) The passage from the back of the mouth to the pharynx, bounded by the soft palate, the base of the tongue, and the palatine arches. [Middle English, from Latin faucēs.]
Which muscle functions to elevate the posterior portion of the tongue and narrow the fauces?
The fibers run downward, laterally, and forward to insert into the posterior and lateral part of the tongue. When the palatoglossal muscle contracts, it pulls the sides of the tongue up and back, pulls the soft palate down on the lateral edges, and narrows the space between the left and right anterior faucial pillars.
What does the palatine tonsil do?
The function of the palatine tonsils is thought to be associated with preventing infection in the respiratory and digestive tracts by producing antibodies that help kill infective agents. Frequently, however, the tonsils themselves become the objects of infection, and surgical removal (tonsillectomy) is required.
What keeps trachea from collapsing?
The trachea, commonly called the windpipe, is the main airway to the lungs. … The hyaline cartilage in the tracheal wall provides support and keeps the trachea from collapsing. The posterior soft tissue allows for expansion of the esophagus, which is immediately posterior to the trachea.
What are the Faucial pillars?
The right and left palatoglossus muscles create ridges in the lateral pharyngeal wall, referred to as the palatoglossal arches (anterior faucial pillars). These pillars separate the oral cavity and the oropharynx — the muscle functions as an antagonist to the levator veli palatini muscle.
What is Passavant’s Ridge?
The bulge of posterior pharyngeal wall that meets the soft palate is called Passavant’s ridge. … Passavant’ s ridge was first described by Philip Gustav Passavant (1815- 1893), a German surgeon, when he noted the formation of a pad on the posterior pharyngeal wall in a patient with an unrepaired cleft palate.
What is the Stylopharyngeus?
The stylopharyngeus muscle is a long, slender and tapered longitudinal pharyngeal muscle that runs between the styloid process of the temporal bone and the pharynx and functions during the pharyngeal phase of swallowing.

What is the difference between throat and esophagus?
The esophagus is a muscular tube connecting the throat (pharynx) with the stomach. The esophagus is about 8 inches long, and is lined by moist pink tissue called mucosa. The esophagus runs behind the windpipe (trachea) and heart, and in front of the spine.
What comes first pharynx or esophagus?
The pharynx, or throat, is the passageway leading from the mouth and nose to the esophagus and larynx.
What is oral cavity proper?
(OR-ul KA-vih-tee) Refers to the mouth. It includes the lips, the lining inside the cheeks and lips, the front two thirds of the tongue, the upper and lower gums, the floor of the mouth under the tongue, the bony roof of the mouth, and the small area behind the wisdom teeth.
What are the 2 basic divisions of the oral cavity?
The oral cavity is surrounded by the lips and is composed of two separate regions, the vestibule, the area between the cheeks, teeth, and lips, and the oral cavity proper.
What is the Palatine Aponeurosis?
The palatine aponeurosis is a thin, fibrous lamella comprising the extended tendons of the tensor veli palatini muscles, attached to the posterior border and inferior surface of the palatine bone.
How do I keep my pharynx healthy?
- Getting rest.
- Avoiding alcohol.
- Drinking warm liquids, such as lemon tea or tea with honey.
- Gargling with warm salt water (1/2 tsp of salt in 1 cup of water) throughout the day.
- Drinking cold liquids or sucking on fruit-flavored ice pops.
Where is your pharynx located?
Where is the pharynx? The pharynx is in the middle of the neck. It starts at the bottom of the skull and is about 4.5 inches long.
What is difference between larynx and pharynx?
The main difference between pharynx and larynx is that pharynx is a part of an alimentary canal, which extends from the nasal cavity and mouth to the larynx and the esophagus whereas larynx is the upper portion of the trachea. … The larynx is also called the vocal box since it contains vocal cords.
How do you check for pharyngeal tonsils?
The tongue blade is placed in the center of the tongue at the junction of the anterior two-thirds and the posterior one-third of the tongue. The tongue is firmly depressed, exposing the pharynx. The examiner should note the presence or absence of the palatine tonsils and their size.
Can you see pharyngeal tonsils?
You can’t see them by looking in someone’s mouth. They are at their largest in children between 3 and 5 years old, according to National Health Service. Normally, they start to shrink by age 7 or 8, are barely visible by the late teens and completely gone by adulthood.
What is the lay term for enlarged pharyngeal tonsils?

Where is the Palatoglossal Arch?
n. Either of two ridges or folds of mucous membrane passing from the soft palate to the side of the tongue and enclosing the palatoglossus muscle.
What triggers the swallowing reflex?
The reflex is initiated by touch receptors in the pharynx as a bolus of food is pushed to the back of the mouth by the tongue, or by stimulation of the palate (palatal reflex). Swallowing is a complex mechanism using both skeletal muscle (tongue) and smooth muscles of the pharynx and esophagus.
What muscle elevates the tongue?
The styloglossus originates at the styloid process and blends into the fibers of the inferior longitudinal tongue muscles and the hyoglossus, and elevates and retracts the tongue posteriorly and superiorly. The genioglossus, hyoglossus, and styloglossus are all innervated by the hypoglossal nerve (CN XII).
Which muscle of the tongue elevates the tongue and depresses the soft palate?
The palatoglossus muscle functions to close off the oral cavity from the oropharynx by elevating the posterior tongue and drawing the soft palate inferiorly. It attaches superiorly to the palatine aponeurosis and inferiorly to the side of the tongue.
What are the disadvantages of removing tonsils?
Tonsillectomy, like other surgeries, has certain risks: Reactions to anesthetics. Medication to make you sleep during surgery often causes minor, short-term problems, such as headache, nausea, vomiting or muscle soreness. Serious, long-term problems are rare, though general anesthesia is not without the risk of death.
Do tonsils protect against viruses?
Tonsils are the first line of defense against germs and viruses that enter through the mouth or nose. This makes them vulnerable to infection — tonsillitis.
